This is a two year project with the intent being to provide improved site index estimates for timber supply review 3. The project is a 3 phase project: Phase I: develop preliminary site index estimates across the population of interest, Phase II: install randomly selected ground samples in the population of interest, Phase II: adjust the preliminary site index estimates with the ground sample estimates. Phase I was completed in the previous fiscal year, Phase II and III will be completed in 06/07. In 2006-07 the crews will implement the field program (approximately 70 plots). The contractor will complete the statistical adjustment of the Phase I estimates. As committed to in the sample plan, the contractor will also complete a comparative analysis of the results of the Kingcome SIA program against SIA programs completed on adjacent management units.prepared by Timberline Natural Resource Group.
